THE TRIBE CHALCIDIlSri — BURKS 285 



shorter, 11 three-quarters length of 10, 12 and 13 considerably shorter 

 than 11 but quite variable in exact size ; scrobe cavity rather shallow, 

 edge carinate on ventral margin and ventral one-third of lateral 

 margins; interantennal projection with a narrow, apical lamina; 

 lateral carinae of frons wanting; entire frons deeply and densely 

 punctured, and provided with long setae; frontal tentorial pits 

 located near antennal bases, slightly dorsad of antennal bases ; width 

 of malar space slightly more than one-third height of compound eye ; 

 frontogenal suture extending in a low arc from compound eye to 

 dorsal articulation of mandible; combined widths of compound eyes 

 two-thirds width of interocular space at level of antennal bases ; both 

 mandibles with three teeth; diameter of posterior ocellus slightly 

 less than one-half width of interocellar space. 



Dorsum of thorax densely punctured, lateral punctures slightly 

 larger than mesal ones, areas between punctures varying from 

 glabrous to lightly reticulated; pubescence dense, long, fine; antero- 

 lateral angles of pronotum only faintly carinate, anterior dorsal 

 margin without a carina on mesal three-quarters, a rounded projection 

 present near each posterior laterodorsal angle of pronotum; parap- 

 sidal sutures partly obscured by punctures; prepectus not visible; 

 apex of mesoscutellum provided with a minute lamina; metepi- 

 sternum broad, shallowly pitted, areas between pits glabrous, sparsely 

 covered by long setae; metacoxae glabrous, very slender near apex, 

 sparsely covered by long pubescence; metafemora glabrous, outer 

 surface covered by short pubescence, ventral margin arcuate, with 

 12 to 16 minute, blunt, widely spaced teeth ; inner tooth lacking ; apex 

 of metatibia acute, slightly curved dorsad. 



Propodeum densely covered by long, slender setae, carinae strong, 

 but irregular, enclosing nearly quadrangular areas, one very slight 

 lateral tooth present on each side near point of insertion of petiole, 

 spiracular openings large, extending obliquely laterad; petiole 

 glabrous or showing very faint shagreening under a strong light, a 

 prominent lateral furrow extending from base to apex on either side, 

 basal lamina narrow, interrupted at dorsolateral angles; gaster 

 strongly flattened, slightly larger than metafemur, prominent lateral 

 rows of setae present on abdominal tergites 3 to 7 ; eighth tergite mi- 

 nutely pitted, covered with long, stout setae, spiracular openings 

 round; cerci oval, located near anterior margin of epipygium and 

 usually bearing three long setae ; apices of ovipositor sheaths densely 

 covered with long setae.
